Be it known that LJOB SHUFFLEBO'I'IOM MORRISS, manufacturer, a subject of the Queen of Great Britain, residing at 57 to 59 Ludgate Hill, in the city of London, England, have invented a newand useful Improvement in Rotary Printing-Machines, (for which I have applied for a patent in Great Britain,

No. 24,944, bearing datethe-15th of Decem ber, 1899,) of which the following is a full and complete specification.

This invention relates to rotary algraphic, lithographic, or surface printing machines; and it consists in the introduction of one ormore rollers of any suitable absorbent material placed between the water-rollers and the inking-rollers to operate in contact with the printing-plate, the object being to absorb the superfluous water or moisture from the said plate, which water or moisture has hitherto been taken off by the inking-rollersand be came incorporated with the ink, which was hardened thereby and otherwise deteriorated the quality of the printing. v

In the accompanying drawings,- which show two methods of carrying the invention into. practice, Figurel is a diagrammatic view, in side elevation, of arotary algraphic or lithographic printing machine fitted with this in vention. Figs. 2 and 3 are broken views, partly in section, of the absorbent roller; and Figs. 4, 5, and 6 are similar views to the above, showing a modification.

Similar letters refer to similar parts throu ghout the several views.

A designates the curved printing surface.

the ink plate or slab B occupying the greater part of the remaining curved surface.

0 C are the inking-rollers, so mounted as to' revolve in contact with the ink plate or slab B and the printing surface or plate A.

D is the impression-cylinder.

In order to dam-pen or moisten the surface of the plate'Abefore it is inked, there are ar- Accordin'g tothe present invention for the purpose of removing the-excess water or-moisture left by the water-rollers'E from the printforming. part of Letters 2mm m5. 664,965, datedianuary 1,- 1901.
